Printing Process

• Over print/Wet print

• Over #print /Wet print is a kind of printing directly on white fabric or on pre-dyed fabric. The latter is called overprinting (also called dyeing printing), of course, the color of the printed #pattern is much darker than the dyed background. About 80% of the printed fabrics on the market use direct printing.

• Discharge print

• Use dyes that are not resistant to discharge agents to dye the base color. After #drying, use a color dye printing paste that contains discharge agents or at the same time. During post-processing, the ground color dyes in the #printing area are destroyed and faded. The white pattern formed on the colored ground (called white discharge printing) or the colored pattern formed by dyeing with colorful dyes (called color discharge printing). Also known as Pabai or Seba.

Compared with direct printing, the production cost of discharging #fabrics is very high, and the use of reducing agents must be carefully and accurately controlled

• Burn-out print

Burnt-out printing refers to the chemical substances that can destroy the fiber structure #printed on the pattern. Therefore, holes will be formed in the contact between the chemical and the fabric. The edges of holes in burnt-out prints are always worn prematurely, so this fabric has poor durability.

Another type of #burnt-out printing is that the #fabric is made of blended yarn, core yarn, or interwoven fabric of two or more fibers. Chemicals can destroy one fiber (cellulose), leaving the others undamaged. Fiber. This printing method can print many special and interesting printed fabrics.

• Foaming print

The printing method is used to locally apply chemicals that can swell or shrink the fibers on the fabric, and through proper treatment, the difference between the expansion or contraction of the fibers in the printed part and the fiber in the non-printed part can be obtained, so as to obtain a product with regular uneven surface patterns. Such as cotton printed seersucker with caustic soda as bulking agent. Also called bump printing.

The foaming temperature is generally 110C, the time is 30 seconds, and the 80-100 mesh screen is used for printing.

• Pigment print

Since the coating is a water-insoluble coloring substance and has no affinity for fibers, its coloring must be achieved by coating with a film-forming polymer compound (adhesive) and adhesion to fibers.

#Pigment printing can be used in the processing of any fiber #textiles, and it is more advantageous in the printing of blended and interwoven fabrics. It has simple process, wide chromatogram, clear flower shape outline, but poor hand feeling and low rubbing fastness.

Pigment printing is direct printing with paint. This process is usually called dry printing to distinguish it from wet printing (or dye printing).

Their light fastness and dry-cleaning fastness are good, even excellent, so they are widely used in decorative fabrics, curtain fabrics and clothing fabrics that require dry cleaning.
